Single Command Database Setup
Kamran Ahmed Improve this Guide
When you are working on a backend application, you are likely to need a database. You can either install it on your machine or use a Docker container. I prefer to use Docker containers because it is easier to setup and doesn’t pollute my machine with unnecessary dependencies.
This short guide will show you how to spin up a MySQL, PostgreSQL, or MongoDB instance on your local machine using docker. Feel free to submit a PR adding more databases.
PostgreSQL
You can run the following command to run PostgreSQL in a Docker container:
docker run \
--name pg \
--detach \
--publish 5432:5432 \
--env POSTGRES_PASSWORD=admin \
postgres
Now you can connect and run commands against the instance using the following:
docker exec -it pg \
psql -U postgres
MySQL
You can run the following command to run MySQL in a Docker container:
docker run \
--name ms \
--publish 3306:3306 \
--detach \
--env MYSQL_ROOT_PASSWORD=admin \
mysql
Now, you can use the following to run commands against the MySQL instance:
docker exec -it ms \
mysql -u root -padmin
MongoDB
You can run the following command to run MongoDB in a Docker container:
docker run \
--name mdb \
--publish 27017:27017 \
--detach \
mongo
Now, you can use the following to run commands against the MongoDB instance:
docker exec -it mdb \
mongo
